If the clutter on your property says one unit isn't enough, but your wallet disagrees, supplement your main unit with one of the less expensive, smaller models. There are three main types of such units, all of which go by descriptive names. $Corner sheds$ are made to fit precisely into a corner and run about 3 feet tall by 3 feet wide by 2 feet deep. Meanwhile, either a $vertical shed$ (5 x 3 x 4) or a $horizontal shed$ (3 x 5 x 4) may be just the handy outdoor storage building to fill your need for additional space.
Utilized Pegboards - Pegboards are a great tool that can be used almost anywhere in the home for organization. The same is true for your shed. For small tools, such as hand shovels and rakes, attach a pegboard to a wall and use various hooks and hangers to place hand tools and other items on. This gets them off the ground, out of the way and in a consistent spot that is easy to find.
